Answer:
∴The air cannot be made to flow in with the given pump at the given conditions.
Explanation:
Given:
- gauge pressure of bicycle tyre,
- length of cylinder of the pump,
- area of the the cylinder of the pump,
- we have the density of air at STP,
The piston must be pushed more than the pressure inside the tyre:
∴The air cannot be made to flow in with the given pump at the given conditions.
Answer:
B)5.52x10^9 J
Explanation:
The equation for calculating kinetic energy is as follows
E=
so what we have to do is calculate the kinetic energy of the space probe in each state and calculate the difference
E=
E=
E=(1500)(5000^2-4200^2)/2
E=5.52x10^9 J
The resistance of a 2 m long tungsten wire whose cross-sectional area of 0.15 mm² will be 0.74 ohm.
<h3>What is resistance?</h3>
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
ρ is the resistivity of tungsten = 5.6×10⁻⁸ (ohm m)
The relation of resistance with length and thickness is given by ;
Hence, the resistance of tungsten wire will be 0.74 ohm.

Determine the distance moved
First, we need to determine the acceleration.
Solve for a
Next, we determine the distance using:
Since it starts from rest,
So:
